Xen devel - Aug 2009 - With latest Qemu and Xen-3.4, VT-d does not work

Hi, list, 
	I just tried Xen-3.4 with latest QEMU, but it seems that VT-d does not work
properly. Devices could be hidden through PCIBACK, but could not be assigned to
guest (Linux guest cannot see the device through ''lspci'').
VT-d works well with Xen-3.4 and its corresponding QEMU, also it works well with
latest Xen upstream and latest QEMU.
 
Best Regards, 
-- Dongxiao

Interfaces between toolstack and qemu, particularly for passthru, keep
changing. 3.4 and latest qemu will not be compatible.
